Brookville Lake is southeastern Indiana’s largest reservoir and the primary recreational boating destination for the Cincinnati-Indianapolis corridor — a 5,260-acre U.S. Army Corps of Engineers impoundment on the Whitewater River in Franklin County that sits just 50 miles northwest of Cincinnati and 75 miles southeast of Indianapolis in the rolling Whitewater River valley. Created by Brookville Dam in 1974, the lake stretches through the forested hills of southeastern Indiana with 158 miles of shoreline that remains significantly less developed than comparable reservoirs closer to major metropolitan areas — the surrounding Brookville Lake State Recreation Area and the Whitewater Memorial State Forest protect substantial portions of the shoreline and give the lake a natural wooded character that feels genuinely removed from the Cincinnati suburban landscape just an hour away. The Whitewater River watershed — one of Indiana’s cleaner river systems flowing from the agricultural uplands of eastern Indiana through the forested valleys of the Cincinnati Arch geological formation — creates water quality conditions that support a genuinely productive fishery and recreational boating experience. The Old National Road — U.S. Route 40 — crosses the Whitewater River valley just north of the lake corridor, giving Brookville a connection to one of America’s most historically significant travel routes that drew settlers westward through Indiana from the early 1800s onward.

The fishing on Brookville Lake is consistently strong across multiple species and has established the reservoir as the most productive inland Indiana lake in the southeastern part of the state. Largemouth bass are the primary tournament target — the lake’s rocky bluff banks, the submerged timber in the Whitewater River arm, and the cove and creek arm structure throughout the 158-mile shoreline produce quality largemouth consistently and draw organized tournament events from across southeastern Indiana. Musky are stocked by the Indiana Department of Natural Resources and produce an exciting trophy fishery that draws dedicated musky hunters from across the Cincinnati and Indianapolis corridor who specifically target Brookville for its improving big fish opportunities. Striped bass stocked by the IDNR grow to impressive sizes in the productive warm basin. Walleye, crappie, white bass, bluegill, and channel catfish round out a year-round warmwater fishery.

Brookville Lake’s position between Cincinnati and Indianapolis makes it one of the most geographically convenient large reservoir destinations for boaters from either metropolitan area — 50 miles from Cincinnati and 75 miles from Indianapolis means a genuine day-trip lake for both markets simultaneously. The Whitewater Memorial State Forest shoreline on the lake’s western reach has specific no-motor zones and seasonal wildlife protection areas — check current Indiana DNR regulations at in.gov/dnr before launching in unfamiliar shoreline sections during the spring nesting season.

Book motor service in Brookville or Liberty before the Memorial Day weekend — the combined Cincinnati and Indianapolis day-tripper traffic compresses the spring service window and local shops handle peak demand in the same narrow April and May window.
